Micropatterned Scintillator Films With Engineered Cs3Cu2I5/CsCu2I3 Nanocrystals for Low‐Crosstalk X‐Ray Imaging at Clinically Relevant Tube Voltage

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Polyethylene glycol‐coated, lead‐free CsCu2I3 nanocrystal scintillator films achieve superior X‐ray imaging resolution over unpatterned films at 80 kVp by reducing crosstalk through lithographic micropatterning and optimized thickness control. The spatial resolution of X‐ray imaging is often limited by radioluminescence scattering, which is exacerbated

A2A Adenosine Receptor Agonists With Last‐Step Enzymatic 18F‐Labelling Potential (Fluorinase) for Positron Emission Tomography (PET)

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
This study exploits the comparable binding tolerances between the fluorinase enzyme and the A2A adenosine receptor towards the development of novel C‐2 functionalised 5′‐fluorodeoxy‐adenosine (FDA)‐based agonists with enzymatic 18F‐labelling capability for positron emission tomography (PET).

Prediction of Ignition Possibility of Self‐Regulating Heating Cable Using Current Signature Analysis

open access: yesFire and Materials, EarlyView.
ABSTRACT A self‐regulating heating cable (SRHC), which has the advantages of ease of use and economic feasibility, is widely used in various industrial processes to prevent the freezing of pipes and maintain temperature. However, if the SRHC, a heating element, loses its temperature control ability due to internal and external factors, it may ignite ...

Enhanced blue emission in silica‐confined mixed‐halide perovskite quantum dots via releasing residual stress

open access: yesInfoMat, EarlyView.
Residual tensile stress is identified as a key factor responsible for the low luminous efficiency in silica‐confined blue‐emitting CsPb(Cl/Br)3 quantum dots. A hydrothermal treatment enables stress release in these quantum dots and significantly enhances their luminous efficiency.
